Answer:
480
Explanation:
resistance equals to potential difference divide by electric current
120÷0.25
=480
It’s will be B because the circuit had a open or close so if that doesn’t work than it’s because it’s open
92 percent because you multiply it by 2
Answer:
The bulb B glows brighter.
Explanation:
Given that,
A glows brightly and B glows dimly.
According to ohm's law,
Two light bulbs A and B are connected in series to a battery then the current will be same in both bulbs and the resistance is high of bulb A and low in bulb B.
If bulb A connect to a battery and bulb B connect to a same battery separately.
Then bulb B glows brighter because the resistance is high in bulb A so the current will be low.
The resistance is low in bulb B so the current will be high.
Hence, The bulb B glows brighter.
