the answer is D i think..cozPlease help!
How much energy is converted in a resistor of 5 ohms carrying a current of 2 A for 10 s
A : 4j
b : 25j
c : 100j
d : 200j
No problem. Just wait , u ll get it tomorrowmay 2014 paper 1 ?
Yep sorry i used time 5 sthe answer is D i think..coz
P=IV..so uv 2 find d voltage first...u do..V=RxI=2x5=10V
P=2X10=20W..so..E=PxT..so...2oWx10s=200j
yeah!..u understood rit...hw???so the answer is D not C ?
nxt tym be careful wn u reply 2 odrs..ny1 cn mk mistakes so its alrit!Mr.PHYSICS GENIUS!Yep sorry i used time 5 s
