What scale must a dmm have to measure current in a circuit?
ohms law babe voltage,current & resistance
What are watts amps and ohms?
ohms is a measure of resistance(R) in a circuit. Watts is a measure of the power(P), in this case lets assume it is the power used by the resistive element (lamp, heater etc). Power(watts)=Current(Amps)x Current(amps) x Resistance(ohms) or Resistance (ohms)=Power(W)/(current x current)
Voltage drop - explanation in terms of electrons?
If you had a simple circuit of one hot wire (10 ohms), a load (100 ohms), and a neutral wire (10 ohms) at 120 volts; total resistance would be 120 ohms, divide 120 volts by 120 ohms = 1 amp (electrons), current stays the same in a series circuit, so 1 amp would flow through each part of the circuit, 1 amp times 10 ohms equals 10 volts dropped on each wire, 120 - (10 + 10) = 100 volts left for the load, 1 amp through the 100 ohm load proves this
How many volts is 600 ohms?
None. 600 ohms is not a measure of electrical charge (which is what voltage is). Volts = current times resistance.
How much resistance should be on a 5.0 kw heat strip?
Depends on the voltage. Wattage is Volts x Amps. Resistance (ohms) is Volts divided by Amps. So on a 120V circuit, it would draw 41.66 amps. To do that, it would need a resistance of 2.88 ohms. But on a 240V circuit, it would draw 20.83 amps. That would require a resistance of 11.52 ohms. Determine the circuit voltage, then use that to figure the amps, then use that result to calculate the resistance necessary.
Can you measure ohms from a live 115v AC outlet?
No, the circuit should not be energized when checking the resistance of a circuit.
How do you measure volts amps and ohms?
Preferably with a multimeter. For amps you hook it up in series, for volts you hook it up in parallell. For Ohms, you'll need to have the item you want to measure separated fron the circuit.
What scale must a dmm have to measure current in a circuit?
ohms law babe voltage,current & resistance
In a parallel circuit the smallest resistor is 500 ohms. What is the largest value this parallel circuit can have?
500 ohms.
What is the total resistance of a series circuit with 5ohms10 ohms 20 ohms?
35 ohms
There are three sources of resistance in a parallel circuit two of them are rated at 20 ohms the other at 10 ohms what is the circuit's total resistances?
5 ohms.
What are watts amps and ohms?
ohms is a measure of resistance(R) in a circuit. Watts is a measure of the power(P), in this case lets assume it is the power used by the resistive element (lamp, heater etc). Power(watts)=Current(Amps)x Current(amps) x Resistance(ohms) or Resistance (ohms)=Power(W)/(current x current)
How do you determine shorted resistor?
A short circuit is an unexpected path of zero resistance between two nodes in a circuit. If you measure the resistance of a resistor, and find that is has zero ohms, but the resistor is supposed to be somthing else, such as 100 ohms, then you can conclude that the resistor is shorted. Keep in mind that the precision of the measurement might be critical. If the resistor is supposed to be 100 ohms, but you get zero ohms, then the answer is easy. If the resistor is 0.001 ohms, but you get zero ohms, then you have to consider the precision of the measurement, the resistance of the wires, etc.
The total resistance for this circuit if all resistors are 200 ohms is?
400 ohms
Is a megohm a short circuit?
No. A short circuit would be zero ohms.
A series circuit has individual resistor values of 200 ohms 86 ohms 91 ohms 180 ohms and 150 ohms What is the total resistance of the circuit?
In a series circuits, you simply add the the values of each resistor and that is you answer. i.e. - 200 + 86 + 91 + 180 + 150 = 707 ohms
Is resistance in a series circuit equal to the largest resistor in the series?
No. The resistance in a series circuit is all the resistor values added together. eg. If two resistors were in a circuit, one was 10 ohms and the other was 30 ohms, the resistance in the circuit would be 30 ohms. Hope this helps!
