If we have two resistors (

A	2
B	13.3
C	60
D	20

Explanation:

Detailed explanation-1: -When resistors R1 and R2 are connected in series across a battery of potential difference V, the power dissipated by the resistors are P1 and P2 respectively. When they are connected in parallel across a battery of potential difference E, the power dissipated is P3 and P4 respectively.

Detailed explanation-2: -The equivalent resistance of a set of resistors in a series connection is equal to the algebraic sum of the individual resistances.

Detailed explanation-3: -When resistors are connected in series, the total voltage (or potential difference) across all the resistors is equal to the sum of the voltages across each resistor. In other words, the voltages around the circuit add up to the voltage of the supply.
