Question:
Two resistors 4 ohm and 6 ohm are connected in parallel. the combination is connected across a 6 volt battery of negligible resistance. calculate - 1.the current through the battery 2. current through each resistor.
Answer:
(1) V= 6V
Req = 1/R1 + 1 /R2 = 1/4 + 1/6 = 5/12 = 12/5 ohm = 2.4 ohm
According to ohms law ,
V = IR
I = V/R
I = 6/2.4
I = 2.5 A
(2)
i)Current through 6 ohm
V = 6 V , R= 6 ohm , I = ?
I = V/R
I = 6/6
I = 1 A
ii) Current through 4 ohm
V = 6V , R = 4 ohm , I = ?
I = V/R
I = 6 /4
I = 1.5 A
