Question

the resistance of 3 ohm 4 ohm and 12 connected in parallel what is the effective resistance of the combination ​

Answer 1

Answer:

Resistance of resistors = 1/(1/4+1/6+1/12) = 2 ohms

Resistance of loop = 2 + 2 = 4 ohms

Current I = V/R = 4 volts/4 ohms = 1 amp

Answer 2

Answer:

$1 \div 12 + 1 \div 4 + 1 \div 3 \: is \: your \: answer$
