Answer : The electrical power is, 250 watts.
Solution : Given,
Electric current = 25 ampere
Voltage = 10 volts
Formula used :
P = electric power
I = electric current
V = voltage
Now put all the given values in this formula, we get
Therefore, the electrical power is, 250 watts.
when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
