Concept explainers

HVDC

HVDC stands for high voltage direct current in the electric power transmission system. The high voltage direct current system uses direct current (DC) for the transmission of electrical power through transmission lines in contrast with the alternating current that is the AC system. The HVDC is used to transmit bulk power point-to-point through long distances transmission lines. Power is rapidly transferred because the efficiency of transmission lines is greatly increased over long distances due to HVDC lines.

A light bulb is rated for 120 volts and 60 watts (it means that the light bulb dissipates 60 watts if it is connected to 120 volt source). If we connect two of them in series and power them up with 120 volts source as shown below. How much power is dissipated by each light bulb?
3. You are an electrician. You have been asked by a homeowner to install a lighted mirror in a bathroom. The mirror contains eight 40-watt lamps. Upon checking the service panel you discover that the bathroom circuit is connected to a single 120-volt, 20-ampere circuit breaker. At present, the circuit supplies power to an electric wall heater rated at 1000 watts, a ceiling fan with a light kit, and a light fixture over the mirror. The fan motor has a full-load current draw of 3.2 amperess and the light kit contains three 60-watt lamps. The light fixture presently installed over the mirror contains four 60-watt lamps. The homeowner asked whether the present light fixture over the mirror can be replaced by the lighted mirror. Assuming all loads are continuous, can the present circuit supply the power needed to operate all the loads without overloading the circuit?
The EMF of a battery is 4.5 volts. When it is connected to an external resistance of 12 ohms, the TPD is 4.3 volts. What is the internal resistance of the battery?
For the circuit shown, calculate the total current and voltage drop value at each of the resistors, given a power supply of 12 volts. Measure the current flowing through the circuit and measure the voltage drop in each resistor.
For the circuit below, determine the circulating current if the supply is 5 volts and the resistor is 10k ohms.
