Answer:
120 V
Step-by-step explanation:
Given:
I (total) = 0,5 A
R1 = 110 Ω
R2 = 130 Ω
Find: V (total) - ?
The resistors are connected in series
That means, the current in the circuit is the same for every resistor:
I (total) = I1 = I2
Now, we need to find the voltage in each resistor:
V1 = I × R1
V1 = 0,5 × 110 = 55 V
V2 = I × R2
V2 = 0,5 × 130 = 65 V
Now, since the connection is in series, in order to find the total voltage in the circuit, we have to add the voltages of the resistors:
V (total) = V1 + V2
V (total) = 55 + 65 = 120 V
