Question

A Sapling Learning For the circuit shown to the right, determine the magnitude of the currents iz, b, and 4 assing through batteries 2 3, and respectively. In each case, determine whether the lying power or being charged. The batteries and resistors in the circuit are attery is properties assumed to be ideal and have the following E, 27.0 v E, 3.00 V E, 22.5 V E, 3.00 V R, 27.0 Q R, 12.0 R, 82.0 Q Number O supplying power A O being charged Re O supplying power Number A O being charged Number O supplying power A O being charged

Explanation / Answer

here,

using KVL in the left side loop

I3 * R3 = E3

I3 * 82 = 22.5

I3 = 0.27 A

using KVL in the right side loop

(R2 + R1) * I2 = E2 + E4 - E1

(27 + 12) * I2 = 3 + 3 - 27

I2 = 0.54 A

and using KCL

I4 = I2 - I3

I4 = 0.27 A
