You just have to put the new value and you will get the new value of IL. If.

## How do you find RL in Thevenin?

Thevenin's Theorem in Action Find the Thevenin Resistance by removing all voltage sources and load resistor. Find the Thevenin Voltage by plugging in the voltages. Use the Thevenin Resistance and Voltage to find the current flowing through the load.

## How do you find the Vth of a circuit?

This is the equivalent Thevenin circuit of that linear electric network or complex circuit which had to be simplified and analyzed by Thevenin's Theorem. You have done it. Now find the Total current flowing through the load resistor by using the Ohm's Law: IT = VTH / (RTH + RL).

## What is ETH in circuit?

Use KCL, KVL and Ohm's Law as needed to calculate the open circuit voltage across the output terminals. This open circuit output voltage is (ETH), the Thevenin voltage source magnitude.

## How do you find the load value of a resistor?

We'll use the following formula to determine the resistor value: Resistor = (Battery Voltage – LED voltage) / desired LED current. For a typical white LED that requires 10mA, powered by 12V the values are: (12-3.4)/. 010=860 ohms.

## How do you calculate load current?

I= P/(1.732*V*Cos pi) Here three-phase full load current is equal to the power divided by 1.732 times of line to line voltage and power factor.

## Is RTh and RN same?

The Norton equivalent resistance (RN) is equal to the Thévenin equivalent resistance (RTh). Calculate RTh as described in step 2 in the Thévenin equivalent circuit. and RN = RTh. The Thévenin equivalent circuit is the source transformation of the Norton equivalent circuit.

## How do you calculate load voltage?

Calculating an Electrical Load in a Simple Circuit Let Power = Voltage * Current (P=VI). Let Current = Voltage/Resistance (I=V/R). Apply Kirchoff's Second Law, that the sum of the voltages around a circuit is zero. Conclude that the load voltage around the simple circuit must be 9 volts.

## How do you find Zth in an AC circuit?

To find Zth: Remember that when dividing two angles you subtract the denominator from the numerator, when multiplying two angles you add them.

## How do you find the missing resistor in a series circuit?

Calculating Resistance of Unknown resistor, total current and voltage across each resistor

1. – Resistance of R2. Since it is given that total power is 60 watts, and the series circuit has 120v, then we can calculate total resistance to be RT = (120*120)/60 = 240 ohms. …
2. – Current in the circuit. …
3. – Voltage across each resistor.

## What is load resistance in a circuit?

Load Resistance Defined At the most basic level, load resistance is the cumulative resistance of a circuit, as seen by the voltage, current, or power source driving that circuit. This includes the resistance of the wires and the resistance of any devices connected to those wires.

## How do you find the load current of a battery?

The key is to use the watts you know to calculate the amps at the battery voltage . For example, say you want to run a 250 watt 110VAC light bulb from an inverter for 5 hours. Amp-hours (at 12 volts) = watt-hours / 12 volts = 1470 / 12 = 122.5 amp-hours.

## How do you calculate maximum demand load?

Maximum demand Calculation: Maximum Demand= Connected Load x Load Factor / Power Factor.

## How do you find the load on a circuit?

1. Add together the wattage capacity of all general lighting branch circuits.
2. Add in the wattage rating of all plug-in outlet circuits.
3. Add in the wattage rating of all permanent appliances (ranges, dryers, water heaters, etc.)
4. Subtract 10,000.
5. Multiply this number by . …
