The potential difference between the terminals of an electric heater is \(55\ V\) when it draws a current of \(2\ A\) from the source. What current will the heater draw if the potential difference is increased to \(130\ V\)?
[Note: Enter the answers as a whole number.]
According to Ohm's law, the value of resistance is
On substituting the known values, the resistance of electric circuit is found to be
When the potential difference is increased to \(130\ V\), the current is given by the formula
On substituting the known values, the current flowing through the heater is found as \(A\)
