its length – the longer the wire, the greater its resistance. its cross-sectional area A – the greater the area, the less its resistance. the resistivity of the material r – the greater the resistivity, the greater its resistance.

The main uses of a multimeter are to measure the three electrical characteristics: voltage, current, and resistance.

Ohm's law is the most important, basic law of electricity. It defines the relationship between the three fundamental electrical quantities: current, voltage, and resistance.

Resistance is a constant pushback against electrical force, much like friction. Inductance is resistance to a change in electrical force, much like inertia. If current flows through a circuit with high inductance, the current will continue flow at a similar rate, resisting any changes to the flow.

The makeup of individual cables varies according to application. The construction and material are determined by three main factors: Working voltage, determining the thickness of the insulation; Current-carrying capacity, determining the cross-sectional size of the conductor(s);

The relationship between voltage, current, and resistance is described by Ohm's law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.

1. ESSENTIAL REQUIREMENTS OF GOOD HEATING ELEMENT High-specific resistance so that small length of wire may be required to provide given amount of heat. High-melting point so that it can withstand for high temperature, a small increase in temperature will not destroy the element.

First, the total length of the wires will affect the amount of resistance. The longer the wire, the more resistance that there will be. ... Wider wires have a greater cross-sectional area. Water will flow through a wider pipe at a higher rate than it will flow through a narrow pipe.

The relationship between Potential Difference, Resistance, and Current is given by Ohm's Law, which states that: The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R.
