Electrical voltage is the potential energy of an electrical supply stored in the form of an electrical charge. From the equation I = V/R, the current flowing through a circuit is directly proportional to the voltage and inversely proportional to the resistance.Therefore, the voltage of the current increases as it passes through a resistor.
Answer:
Frequency
Explanation:
The intensity of light is increased by increasing the number of photon per second, and the number of photon per second is referred to as frequency. A photon the smallest unit of light. If the frequency is increased, the number of photons per second increases hence an increase in intensity.
