In a circuit voltage and current are
WebMar 15, 2024 · The open-circuit voltage is equal to the voltage across a 6-ohm resistor. So, we need to find the current passing through the 6-ohm resistor. Now, apply KVL in outer loop; (1) We can express 3A current source in terms of loop currents. (2) Now, by solving eq-1 and eq-2, we can find the current I 1 and I 2. WebA circuit is a loop through which current can flow. A power source, such as a battery, provides the energy for the circuit to work. Electrons flow from the negative side of the power source, through the circuit and back to the positive side of the power source. Once the electrons return to the power source, the circuit is complete.
