There are three resistors joined in series in a system having resistance equal to 10ohm, 20ohm and 30 oum respectively.
If the potential difference of circuit is 240v, find the total resistance and current through the circuit.
Dear Student
R1 = 10 Ω
R2 = 20 Ω
R3 = 30 Ω
V = 240 V
R = 10Ω + 20Ω + 30Ω = 60 Ω
Electric current I = V/R
I =240 V ÷ 60 Ω
I = 4 A
Total resistance (R) = 60 Ω
R = 60 Ω
Current through the circuit = 4 A
