I got V1=18V
Here's my work:
I got V1 = 37.33V, Vx= 13.33V. It checks when you plug the numbers into your schematic.
Also, if two loops, why did the OP have - and + signs next to that line?
Voltage is a measure of the potential energy difference between two points in an electrical circuit. It is measured in volts (V) and represents the force that drives electrical current through a circuit.
Voltage is calculated by dividing the energy (in joules) by the amount of charge (in coulombs) in an electrical circuit. This is represented by the equation V = E/Q, where V is voltage, E is energy, and Q is charge.
Voltage and current are two fundamental concepts in electricity. While voltage is a measure of potential energy, current is a measure of the rate at which charge flows through a circuit. Voltage can be thought of as the force that drives current through a circuit.
Voltage is measured using a voltmeter, which is a device that measures the potential difference between two points in an electrical circuit. It is typically connected in parallel to the circuit and displays the voltage in volts (V).
Finding the voltage across 2 nodes in a circuit is important because it helps us understand the behavior and efficiency of the circuit. It also allows us to calculate the power, resistance, and current in the circuit, which are essential for troubleshooting and optimizing the circuit's performance.
