R1=7
R2=11
if a 24-volt battery is connected across R1 and R2 in series, Find the circuit current. amps

430
1.3
5.6
0.75

Answer 1

1.3 Amps

Step-by-step explanation:

We are given;

A circuit with resistors, R1 and R2

R1 = 7 Ω

R2 = 11 Ω

Voltage = 24 V

We are required to calculate the current in the circuit.

Step 1: We need to find the effective resistance.

When resistors are arranged in series, the effective resistance is calculated by;

Rt = R₁ + R₂ + R₃ + ..........Rₙ

Therefore;

Total resistance = 7 + 11

= 18 Ω

Step 2: Calculate the current in the circuit

From the ohm's law;

V = IR

Rearranging the formula;

I = V/R

Thus;

I = 24 V ÷ 18 Ω

= 1.333 Amps

= 1.3 Amps

Thus, the current in the circuit is 1.3 Amps
