Answer:
25 w is greater
Explanation:
Lets understand electrical terminology.
Watts is unit of Power, so it is volts times Current
Volt is Current times Resistance.
Current is directly proportional to Volts and inversely to resistance of
the circuit.
so 100 watts compared to 25 watts ,definitely former one has lower resistance than the later.
Higher the resistance lower the current ,consequently lower the (volts remain same)power
Lower the resistance higher the current flow consequently higher wattage.
so i guess you got the answer .
