For instance, we have a 1/4 watt resistor or a 20-watt amplifier. Students can use it to gauge their level of understanding of circuits and to reflect on what still needs to be understood. The chapter begins with essential definitions of such terms as power factor, phasor, impedance, and per-unit value . Also, for a fully resistive circuit, we always have an in-phase voltage and current, so we can find the power consumed at any instant by multiplying the voltage by the current. In one associated hands-on activity, students build and investigate the characteristics of series circuits. In this circuit, the total resistance is load resistance so the R = 2 and the input voltage supply is 12V DC so the V = 12V. Suffice it to say that two of the tiny particles that make up atoms protons and electrons are the bearers . In other words, it is the amount of charge that passes through a point in a circuit per second. In DC circuits, the power of the components is simply the output of the DC voltage times the current in watts.

In this case, where the current and voltage are out of phase by 90, we name reactance as the ratio of voltage to current, and its symbol is X. I. Still, circuits with only resistors are not very exciting and applicable. As they offer an impedance inside a circuit, passive components in AC circuits act quite differently compared to those in DC circuits. The shunt field has a resistance because it is made of wire. Introduction to Series, Parallel and Series-Parallel Connections When a steady direct current flows through a coil, the only opposition to the flow of current is the resistance of the wire from which the coil is made.
