Question

Rearrange the formula current = voltage/resistance to express resistance in terms of current and voltage. Find the resistance of the hair dryer.

Answer 1

From ohm's law:

the potential difference across the conductors is directly propotational to the current flows in that conductor.

i.e.

where R is the resistance of the conductor in ohms.

from the above equation current I=voltage V/Resistance R

then resistance

resistance R=voltage/current

for finding resistance of hair dryer we need the values of power nd voltge (not given)
