Question

Which one has a higher electrical resistance a 100 watt bulb or a 60 watt bulb?; Which one has a higher electrical resistance a 100 watt bulb or a 60 watt bulb?

Answer 1

Answer:

In Series Combination

P= i^2R

I - same

R ~ P

In Parallel Combination

Power = v^2/R

v - same

P ~ 1/R

Answer 2

A 60-watt bulb is more resistant to electricity than a 100-watt bulb

Explanation:

A 60-watt bulb is more resistant to electricity than a 100-watt bulb whereas power is inversely proportional to resistance,i.e if the resistance is high, the power become less .

Inverse proportion:- Relationship between two parameters is inverse proportion when their product is equivalent to a constant value. If the value of one parameter increases, the other one decreases, so that its product remains the same.

For example

power is inversely proportional to resistance

$P \alpha \frac{1}{R}$
