6.5: Electrical Measuring Instruments
In either case, the resistance is measured using Ohm''s law ((R = V/I)) where the voltage is known and the current is measured, or the current is known and the voltage is measured. The component of interest should be isolated from the circuit; otherwise, you will be measuring the equivalent resistance of the circuit.
Voltage vs Current: What are the Similarities & Differences?
Really, "amps" are a measure of electrical current (which is measured in amperes ), and voltage is a term that means electric potential (measured in volts ), but unless you''ve learned the details, it''s understandable that you could get the two confused with each other.
6.12: Battery characteristics
The actual voltage appearing at the terminal needs to be sufficient for the intended application. Typical values of voltage range from 1.2 V for a Ni/Cd battery to 3.7 V for a Li/ion battery. The following graph shows the …
Voltage, Current, Resistance, and Ohm''s Law
The V is the battery voltage, so if R can be determined then the current can be calculated. The first step, then, is to find the resistance of the wire: L is the length, 1.60 m.
