For the circuit shown in the figure (Figure 1) , find the current through and the potential difference across each resistor. Find the current through 4 ? resistor. Find the potential difference across 4 ? resistor. Find the current through 16 ? resistor. Find the potential difference across 16 ? resistor. 5)Find the current through 48 ? resistor. Find the potential difference across 48 ? resistor.Explanation / Answer
R1 = 3 ohm
R2 = 4 ohm
R3 = 48 ohm
R4 = 16 ohms
1/R234 = 1/R2 + 1/R3 + 1/R4
R234 = 3 ohms
Rnet = R1 + R234 = 3 + 3 ohms
potentail diffrerence across R1 =V*R1/(R1 + R234) = 12*3/6 = 6 volts
potentail diffrerence across R2 = (12-6) = 6 volts
potentail diffrerence across R3 = (12-6) = 6 volts
potentail diffrerence across R4 = (12-6) = 6 volts
as the R2,R3,R4 resistors are in parallel
the potentail across them is same
1) cuurent through 4 ohms = 6/4 = 1.5 A
2) 6 volts
3)cuurent through 16 ohms = 6/16 = 0.375 A
4) 6 volts
5)cuurent through 4 ohms = 6/48 = 0.125 A
6) 6 volts
