★Question:—

Calculate the net(equivalent) resistance of the circuit if resistances of 10 Ω, 5 Ω and 15 Ω are connected in parallel.

‡Answer:—

• → 2.72 Ω

Step by Step explanation:—

Here it is given that:—

→ R1 = 10 Ω

→ R2 = 15 Ω

→ R3 = 5 Ω

R1, R2 and R3 are connected in parallel, then equivalent resistance R is given by:—

→ 1/R = 1/R1 + 1/R2 + 1/R3

→ 1/R = 1/10 + 1/15 + 1/5

→ 1/R = 11/30

So,

→ R = 30/11

Therefore,

Equivalent resistance, R = 30/11 = 2.72 Ω
