Question

calculate the current flowing through a wire of resistance 15 ohms connected to 2 cells of 1.5 volts each ​

Answer 1

• Answer

→ Resistance (R) = 15 Ω

→ Potential difference (V) = 2 × 1.5 = 3 V

• Apply formula

→ V = IR (Ohm's law)

→ I = V/R

→ I = 3/15

→ I = 1/5 = 0.2 A

• Current flowing through wire i.e 0.2A
