A p.d. of 6 V is applied to two resistors of 3Ω and 6Ω connected in parallel. Calculate:
(a) the combined resistance
(b) the current flowing in the main circuit
(c) the current following in the 3Ω resistor
(a) ∵ the 3 Ω and 6 Ω resistance are in parallel, hence the eq. resistance = 
(b) I = V/Req = 4/2 = 2A
(c) Current Flowing in 3 Ω resistor =
