Question

(a) the current in each resistor shown in the figure above

Using Kirchhoff's rules, find the following. (1 = 71.0 V, 2 = 60.8 V, and 3 = 79.2 V.)

(a) the current in each resistor shown in the figure above

IR1 = mA IR2 = mA IR3 = mA (b) the potential difference between points c and f magnitude of potential difference     V point at higher potential     2:58 PM Using Kirchhoff's rules, find the following. (epsilon 1 = 71.0 V, epsilon 2 = 60.8 V, and epsilon 3 = 79.2 V.) (a) the current in each resistor shown in the figure above IR1 = mA IR2 = mA IR3 = mA (b) the potential difference between points c and f magnitude of potential difference V point at higher potential

Explanation / Answer

For the left loop,

E1 - E2 - I2R2 + I1R1 = 0

2I1 - 3I2 = -10.2

For the right loop,

E2 + I3R3 - E3 + I2R2 = 0

3I2 + 4I3 = 18.4

For junction f,

I1 + I2 + I3 = 0

Using these three equations,

I1 = 4.671 mA
I2 = 0.2857 mA
I3 = 4.3857 mA   [answers]
