Question

Choice are 1.3 1.0 17​

Answer 1

The current flowing in resistor 1 in the given series circuit is determined as 1.0 A.

Equivalent resistance of the circuit

The equivalent resistance of the circuit is determined as follows;

Rt = R1 + R2

Rt = 15 + 5

Rt = 20ohms

Current flowing in the circuit

The current flowing in the circuit is determined from Ohm's law.

V = IR

I = V/R

I = 20/20

I = 1.0 A

since it is series circuit, same current will flow in R1 and R2.

Thus, the current flowing in resistor 1 in the given series circuit is determined as 1.0 A.
