What is the total dissipative power for a 600 Ohm resistor with 75mA flowing?
Ohm's Law: Volts = Amps * Ohms That means that you have 45 volts across the resistor. Power = Volts * Amps That means that you 3.375 Watts going through the resistor.Alternative AnswerMultiply the square of the current by the resistance.
The value of the resistor has 5 volts across it and has 20mA flowing through it?
The value of a resistor with 5 volts across it and 20 milliamperes of current flowing through it is 250 ohms. Ohm's Law: E = I R R = E/I
If you have a voltage source of 120 volts with a 840 ohm resistor 2000 ohm resistor and a 560 ohm resistor?
I don't see a question. Please clarify if you want an answer.
Voltage drop of 15 Volts across 2.7 killo ohm resistor?
You just stated that the voltage across the resistor is 15 volts, so that's your answer ! If the resistor is connected to a 15-V battery or to the output of a 15-V power supply, then a meter across the resistor is also across the power supply, and reads 15 volts. The current through the resistor is (V/R) = (15/2700) = 5.56 mA. The power dissipated by the resistor (and delivered by the battery) is (V2/R) = (225/2700) = 0.083 watt.
If the current in a certain resistor is 6.2 A and the voltage across the resistor is 110 Vwhat is the resistance of the resistors?
Ohm's Law says Volts = Current x Resistance so R = 110/6.2 = 17.742 Ohms
How do you convert 90 volts to 1.5 volts?
Assuming it's 90 v dc, get a 1.5 k-ohm resistor and an 82 k-ohm resistor. Put them in series across the supply, then there will be slightly over 1.5 v across the smaller resistor.
What is power and current if resistor is 500 ohm?
The question is incomplete without the voltage across the resistor. For example: if V (Voltage across 500 ohm resistor) = 5 Volts, then, Current, I = 5/500 Ampere = 0.01 A.
What is the voltage drop across a 12 ohm resistor with a source of 24 volts?
If there's nothing else between the ends of the resistor and the power supply, then the voltage across the resistor is 24 volts, and the current through it is 2 amperes.
If the volts going in equals 5 and there is a resistance that equals 6 what would be the volts coming out?
The question is a bit ambiguous, but I will try to address it. If the 6 ohm resistance is in series with another resistance then some of the 5 volts would be dropped across the 6 ohm resistance and the remainder of the voltage would be dropped across the other resistance. To calculate the voltage, use the 'resistor voltage divider equation' (Google it). If the 5 volts is applied across only a 6 ohm resistance, then the top of the resistor is at 5 volts and the bottom of the resistor would be at 0 volts. The resistor would drop all of the voltage.

If a current of 2 amps flows through a 12 ohm resistor what is the voltage across the resistor?
The voltage across the resistor can be found using Ohm's law: Voltage = Current x Resistance. Thus, Voltage = 2 amps x 12 ohms = 24 volts.
What is the voltage drop across a resistor of 300 kilo ohm?
What is the amount of current flowing through the resistor? Voltage drop is dependent on the current. Ohm x Amps = Voltage drop
If you have a voltage source of 120 volts with a 840 ohm resistor 2000 ohm resistor and a 560 ohm resistor?
I don't see a question. Please clarify if you want an answer.
A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source. What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor?
The current would be about 20 volts.
What is voltage drop with 30 volts across 25 ohm resistor?
To tell you that we need to know the resistance of the entire circuit.
What voltage is applied to a 4 ohm resistor if the current is 1.5 amps?
Ohm's law: Volts = amps times ohms In the case of a 4 ohm resistor with 1.5 amps of current, the voltage is 6 volts.
