The heating effect of current in a resistor is directly proportional to:
I²R
By Joule's law of heating, the heat produced in a resistor is given by H = I²Rt, so the heating effect is directly proportional to I²R. This is why a higher current or resistance produces much greater heat.
Two resistors of 4 Ω and 6 Ω are connected in parallel. Their equivalent resistance is:
According to Ohm's law, the slope of a V-I graph for a conductor represents
The property of electric current which is applicable in the fuse wires is
An electric current is expressed by a unit called .
What do you call a component of identical size that offers a higher resistance to electricity?
