19.3: Resistance and Resistors

The voltage source supplies energy (causing an electric field and a current), and the resistor converts it to another form (such as thermal energy). In a simple circuit (one with a single simple resistor), the voltage supplied by the source equals the voltage drop across the resistor, since E=qΔV, and the same q flows through each.

This resistance converts part of the electrical energy into heat energy, causing the resistor''s temperature to rise slightly. For a standard, commercially produced resistor, the relationship between (e_{1}-e_{2}) and (i) is linear, with resistance (R) defined as the constant of proportionality (Halliday and Resnick, 1960, Sections 31-2

For each resistor, a potential drop occurs that is equal to the loss of electric potential energy as a current travels through each resistor. According to Ohm''s law, the potential drop (V) across a resistor when a current flows through it is calculated using the equation (V = IR), where (I) is the current in amps ((A)) and (R) is

Parasitic effects are most prominent at high frequencies. For example, a metal foil 1.0 kΩ resistor with 0.05 pF capacitance at 100 MHz would, in fact, behave as a 0.9995 kΩ resistor, when all parasitic effects are considered. This is an example of a good frequency response for a resistor.

A Complete Guide to Resistors

Each resistor has three or four bands specifying the value, plus a tolerance band. For a 4-band resistor, the first two bands are numerical values and the third band is a multiplier. If, for instance, we had a case where the first two bands were red, and the third band was orange, then the resistor value would be 22KΩ.

Power and Energy

When a current flows through a resistor, electrical energy is converted into HEAT energy. The heat generated in the components of a circuit, all of which possess at least some resistance, is dissipated into the air around the components. The rate at which the heat is dissipated is called POWER, given the letter P and measured in units of Watts (W).

How Resistors Work

George Ohm studied the relationship between resistance and the size of the material that was used to make the resistor. He proved that the resistance (R) of a material increases as its length increases. Everytime a current passes through a resistor due to the presence of a voltage across, electrical energy is lost in the form of heat. The

2.8 Power and energy in resistive circuits

2.8 Power and energy in resistive circuits We now consider the power and energy absorbed by resistors and supplied by sources in more detail. Recall that a voltage drop (a decrease in electric potential) across a circuit element in the direction of positive current flow represents energy absorbed. This is the case when current moves through a resistor.

Pre-Charge Resistor

The pre-charge current dissipates power in the resistor. Each successive pre-charge adds more power so if the resistor has not cooled between operations then the temperature will rise. Frequent pre-charge operations will cause the temperature of the resistor to increase, potentially to the point where the resistor overheats and fails.

Keep in mind, however, that a capacitor stores and discharges electric energy, whereas a resistor dissipates it. The quantity (X_C) is known as the capacitive reactance of the capacitor, or the opposition of a capacitor to a change in current. It depends inversely on the frequency of the ac source—high frequency leads to low capacitive
