Three resistors having resistances of `1.60 Omega, 2.40 Omega` and `4.80 Omega` are connected in parallel to a `28.0 V` battery that has negligible internal resistance. Find
(a) the equivalent resistance of the combination.
(b) the current in each resistor.
(c) the total current through the battery.
(d) the voltage across each resistor.
(e) the power dissipated in each resistor.
(f) which resistor dissipates the maximum power the one with the greatest resistance or the least resistance? Explain why this should be.

Answer

A, C, D

Explanation

b. `i=V/R` in each resistance
e. `P=V^2/R` in each resistanc
f. `P=V^2/R`
or `Pprop1/R` (as `V` is same)`
