A bulb is joined to a battery of e.m.f 6V. A steady current of 0.5 A flows through circuit. Calculate the total energy provided by the battery in 5 minutes.

To calculate the total energy provided by the battery, we need to determine the power consumed by the bulb and then multiply it by the time elapsed.

Power (P) is given by the formula:

P = VI

where P is power, V is voltage, and I is current.

Given that the voltage of the battery is 6V and the steady current flowing through the circuit is 0.5A, we can substitute these values into the formula to find the power consumed by the bulb:

P = 6V × 0.5A
P = 3W

The power consumed by the bulb is 3 watts.

Now, to find the total energy provided by the battery in 5 minutes, we can use the formula:

Energy (E) = P × t

where E is energy, P is power, and t is time.

Given that the time is 5 minutes (or 5 × 60 = 300 seconds), we can substitute the values into the formula:

E = 3W × 300s
E = 900 joules

Therefore, the total energy provided by the battery in 5 minutes is 900 joules.

P = Vi

E = Pt
