In this question, there is a resistance in the bulb.
00:05
So this is basically a bulb whose resistance is 3 .5 o.
00:10
And this is connected to the battery.
00:14
The battery voltage is 1 .5 volt.
00:18
This battery flow the current.
00:21
So what is the value of current we are calculated? so we are using omslaw.
00:33
Omslaw states that the current flowing in the conductor is directly proportional to the applied voltage across the conductor.
00:45
So this is the relationship between voltage and current.
00:50
So i is equal to v divided by r because when we remove the directly proportional sign, then its constant will be added.
01:01
So 1 by r is the constant.
01:02
So this is the mathematical relationship between current and voltage...
