Answer:
The voltage of the battery in the flashlight is 600 v
Explanation:
A light bulb provides a resistance of 20 Ω to the 30 A current that runs through it. Determine the voltage of the battery in the flashlight.
To determine the voltage of this battery,all we need to do is to use the formula;
V= IR
where v = voltage
I = current
R= resistance
From the question given;
resistance (I) is given to be 20 while current(I) is 30
We can now proceed to insert our values into the formula;
V= IR
V = 20 × 30
v = 600 v
The voltage of the battery in the flashlight is 600 v
