3. In the Node-Voltage method, we use voltages between the nodes of the circuit and ground. law to solve for the

Three resistors are connected in parallel namely R1, R2 and R3. It is impressed by a source voltage of 120V. If R1 receives 15W while R2 carries a current if 100mA, what should be the value of resistance R3 if the power supplied by the voltage source is 60W?   a. 364.4 ohmsb. 436.4 ohmsc. 43.64 ohmsd. none of these

The wires here have zero resistance. Thus, for currents that travel along a wire that has no circuitelement, you can safely omit it and simplify the circuit. After, you can use the Kirchhoff's rules.

For the circuit find loop currents i1 and i2, as well as voltage vx, by branch current method.

A battery is comprised of 7 cells connected in parallel, each cell has an EMF with 1.4V and an internal resistance of 0.55 ohm. There is a 5.8 ohm load connected to the terminals. Solve for ILoad.
