applying ohm's law we get I =4
p=v/I
p=0.5
p=v/I
p=0.5

Answer:
The maximum power that can be delivered is 2watt.
Power:
- Power is defined as the transfer of energy per unit of time.
- It can also be called the rate of doing work.
- It is calculated as , where W is the work.
- Its SI unit is a watt equal to one joule per second.
Explanation:
Given:
emf (E) = 2V, resistance (R) = 0.5Ω
To find:
Maximum power (P)
Formula:
Solution:
Substituting the given values in the above formula, we get
Therefore, the battery can deliver a maximum power of 2watt to any external circuit.
