Understanding the Electrical Heater's Operation
The behavior of electrical devices like heaters can be analyzed using Ohm's Law, which states that:
V = I × R
Where:
- V = Voltage (Volts)
- I = Current (Amperes)
- R = Resistance (Ohms)
Given Data
- Initial Voltage (V1) = 60 V
- Initial Current (I1) = 4 A
Calculating Resistance
Using the initial values, we can calculate the resistance (R) of the heater:
R = V1 / I1
- R = 60 V / 4 A = 15 Ohms
New Voltage Condition
Now, we need to find out the current (I2) when the voltage is increased to 120 V (V2):
Using Ohm's Law Again
We can express the new current as:
I2 = V2 / R
Substituting the known values:
- I2 = 120 V / 15 Ohms
Calculating I2
- I2 = 8 A
Conclusion
When the potential difference across the heater is increased to 120 volts, the current drawn by the heater will be:
8 Amperes
This demonstrates that current is directly proportional to voltage when resistance remains constant, illustrating the fundamental principles of electrical circuits.
