Three resistors R1, R2, and R3 of 5 ohms, 10 ohms, and 30 ohms, respectively, are connected as follows in the circuit diagram: Calculate: a) the amount of current flowing via each resistor b) the circuit’s total current
Three resistors R1, R2, and R3 of 5 ohms, 10 ohms, and 30 ohms, respectively, are connected as follows in the circuit diagram: Calculate: a) the amount of current flowing via each resistor b) the circuit’s total current

Given,

 

V = 12V

 

R1, R2, and R3 are linked in a series.

 

a) Current through R1 = V/R1 = 12/5 = 2.4 A

 

Current through R2 = V/R2 = 12/10 = 1.2 A

 

Current through R3 = V/R3 = 12/30 = 0.4A

 

b) Circuit total current = 2.4 + 1.2 + 0.4 =4A
