Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If R1 < R2 < R3, and if these resistors are connected in parallel in a circuit, which one has the highest current?
A
R1
B
see
C
Rz
D
All have the same current.
Explanation: 

Detailed explanation-1: -Resistor R1 dissipates the most power E.

Detailed explanation-2: -Thus, the equivalent or resultant resistance of a combination of three resistors, of resistance R1, R2, and R3 joined in parallel is 1Req=1R1+1R2+1R3.

Detailed explanation-3: -Since the resistors R1, R2 and R3 are connected in parallel combination the potential difference across each resistor is same as the supply. Hence VAB = VR1 = VR2 = VR3.

Detailed explanation-4: -We have, Rs=R1+R2+R3. Q. Deduce the expression for the the equivalent resistance of three resistors connected in series.
