How do you find the voltage VX in a circuit?

Find the voltage Vx in the given[/expand] circuit. Sol. From the circuit applying Kirchhoff’s voltage law, we can write 50= 15+ 10+ 15+Vx => Vx= 10V.

How do you calculate the power absorbed by a resistor?

First, we use Ohm’s law ( V = I × R ), to find the current through the resistor. The voltage across the resistor is V = 9 V. The resistance of the resistor is R = 100?. Then, we can use the power rule ( P = I × V ), to find the power dissipated by the resistor.

What does VX mean in circuit?

-You can treat the Vx as an open circuit which means current does not flow through the resistor (meaning it’s a short circuit) and thus from KVL we get Vx = 10V.

How do you calculate power with voltage and current?

The explanations here are that; Current equals Power divided by Voltage (I=P/V), Power equals Current times Voltage (P=VxI), and Voltage equals Power divided by Current (V=P/I).

What is the equivalent circuit with 6-ω and 3-� resistors?

Combining the 6-Ω and 3-Ω resistors in parallel gives 2Ω. Adding the 1-Ω and 4-Ω resistors in series gives 1 + 4 = 5Ω. Transforming the left current source in parallel with the 2-Ω resistor gives the equivalent circuit. *Refer to in‐class illustration, textbook, answer i

What is the difference between removing voltage and current from circuit?

While removing a voltage source, its value is set to zero. This is done by replacing the voltage source with a short circuit. When removing a current source, its value is set to zero. This is done by replacing the current source with an open circuit.

How do you calculate contribution of each source in a circuit?

To calculate the individual contribution of each source in a circuit, the other source must be replaced or removed without affecting the final result. While removing a voltage source, its value is set to zero. This is done by replacing the voltage source with a short circuit.
