How do you measure alternating current voltage and resistance?
You measure current by inserting an amp meter in series with the circuit or using a clamp-on meter to measure current by induction. You measure voltage with a volt meter across the supply. You measure resistance in ohms across the resistance. Luckily all these functions are in the same meter in most cases.
How do you measure the resistance in a parallel circuit?
You have to measure the voltage, and the current. The resistance is then calculated by using Ohm's Law.
How do you measure the unknown resistance?
Measure the voltage V and current I and compute the unknown Resistance R=V/I.
What does the size of a current depend upon?
One way to determine current is to measure it, with an ammeter. Another way is to calculate it using Ohm's law: current = voltage / resistance.
Besides voltage and resistance what else can your multimeter measure?
current
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the ohm unit used to measure?
Ohms measure electrical resistance. The resistance in ohms is the voltage divided by the current.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
How do you change current into voltage?
Compute the open load voltage of the current source across its shunt resistance.This voltage becomes the voltage source's voltage.Move the current source's shunt resistance to the voltage source's series resistance.Insert the new voltage source into the original circuit in place of the current source.
Why is it called multimeter?
since it stands for voltage ohm meter :) can measure voltage current and resistance
How to find resistance?
-- Apply a small, known voltage between the terminals of the device. -- Measure the current through the device with the voltage applied. -- Calculate the resistance of the device. It's (voltage) divided by (current).
