In this section, we will review some of the main topics covered in Schaum's Outline of Basic Electricity, Second Edition (Schaum's Outlines) and provide some examples of solved problems from the book.
Voltage and Current
Voltage is the measure of electric potential difference between two points in a circuit. It is also called electromotive force (emf) or potential. The unit of voltage is the volt (V). Voltage can be generated by various sources, such as batteries, generators, solar cells, or thermocouples.
Current is the measure of the rate of flow of electric charge in a circuit. The unit of current is the ampere (A). Current can be either direct (DC) or alternating (AC). DC current flows in one direction only, while AC current changes direction periodically. The frequency of AC current is measured in hertz (Hz).
The relationship between voltage and current in a circuit is given by Ohm's law, which states that voltage equals current times resistance: V = IR. Resistance is the measure of the opposition to current flow in a circuit. The unit of resistance is the ohm (Î).
Example: A 12-V battery is connected to a resistor with a resistance of 4 Î. What is the current in the circuit
Solution: Using Ohm's law, we can find the current by dividing the voltage by the resistance: I = V/R = 12/4 = 3 A. The current in the circuit is 3 A.
Series and Parallel Circuits
A series circuit is a circuit in which all the components are connected end to end, forming a single path for current flow. The total resistance of a series circuit is equal to the sum of the individual resistances: RT = R1 + R2 + ... + Rn. The total voltage of a series circuit is equal to the sum of the individual voltages: VT = V1 + V2 + ... + Vn. The current in a series circuit is constant and equal to the total current: IT = I1 = I2 = ... = In.
A parallel circuit is a circuit in which all the components are connected across each other, forming multiple paths for current flow. The total resistance of a parallel circuit is equal to the reciprocal of the sum of the reciprocals of the individual resistances: 1/RT = 1/R1 + 1/R2 + ... + 1/Rn. The total voltage of a parallel circuit is constant and equal to the source voltage: VT = VS. The current in a parallel circuit is equal to the sum of the individual currents: IT = I1 + I2 + ... + In.
Example: A 12-V battery is connected to three resistors with resistances of 3 Î, 6 Î, and 9 Î in parallel. What is the total resistance, total current, and current through each resistor
Solution: Using the formulas for parallel circuits, we can find the total resistance by adding the reciprocals of the individual resistances and taking the reciprocal: 1/RT = 1/3 + 1/6 + 1/9 = 11/18; RT = 18/11 Î. The total current is equal to the source voltage divided by the total resistance: IT = VS/RT = 12/(18/11) = 11/3 A. The current through each resistor is equal to the source voltage divided by its resistance: I1 = VS/R1 = 12/3 = 4 A; I2 = VS/R 061ffe29dd
