Question

Select the correct answer
Sam constructs a circuit connects a lead acid battery of 2 v to a lamp of resistance 3 and places an ammeter across it. What must be the
reading of the ammeter?
A 0.66 A
B 0.5 A
C 0.54 A
0.61 A

Answer 1

Answer:

Option A

0.66 A

Explanation:

From Ohm's law, I=V/R where is the current in Amperes, V is the voltage and R is the resistance, from the given information, resistance is 3 Ohms and V is 2 V hence

I=2/3=0.6666667 A

Therefore, the reading on ammeter is 0.66 A
