The resistance is 9 Ohm.
To find the resistance, we need to know about the power in term of resistance and voltage.
What is the value of power in terms of resistance and voltage?
- We know that power=work/time
- Electrostatics work is given as voltage ×charge. So, power=(Voltage×charge)/time
- Again, charge/time is given as current. So, power = Voltage×current
- From Ohm's law, we know that current=voltage/resistance. So, power= voltage ²/resistance.
What is the resistance, if power is 4W and voltage is 6V?
- Resistance in term of power and voltage is given as Resistance= voltage ²/power
- So, resistance=6²/4=36/4= 9 Ohm
Thus, we can conclude that the resistance is 9 Ohm.
