Convert 1000 ohms to amps?
Can not do it without knowing the voltage I = E/R. Amps = Voltage/Ohms.
Formula for ohms law?
ohms=amps/volts Amps= volts/ohms Volts = Amps*Ohms
If voltage is 12 volts and ohms is 0.5 how many amps in circuit?
Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 12 volts / 0.5 ohms = 24 amps
Amps times ohms equal?
voltage! measured in volts. current X resistance = voltage simple ohms law
How many ohms of resistance are in a 120 and ndashvolt hair dryer that draws 7.6 amps of current?
E = I R = 22 x 7 = 154 volts.
Where the V voltage is 12 and the current you is 0.2 amps?
60 Ohms
10 ohms plus 9 volts equals how many amps?
Ohm's Law: Voltage = Amperes times Resistance 9 volts = amps * 10 ohms amps = .9
How do you calculate ohms?
Very basically, simply divide the voltage by the amperage. Thsi is not for calculating Ohms of resistance, just Ohms. For example, a 9 volt battery that delivers 3 amps has 3 ohms. To calculate ohms of resistance we use the ohms law. This measures the difference in current flow in amps (amps/current is amount or volume of flow, volts is power pushing that current, sort of) and voltage. For instance, measure the amps and voltage at the source and record the ohms. Then record the same at the end point the difference in ohms is ohms of resistance. So, if we measure 10 volts and 2 amps at the source we have 5 ohms. at the end point we have 8 volts and 1 amp we have 8 ohms. therefore we have 13 ohms of resistance. 1 Determine current. Current is the flow of electricity measured in amps. For example a current has four amps in the circuit. 2 Determine voltage. Voltage is the difference in electrical potential from two points, measured in volts. For example, there is two-hundred volts in a circuit. 3 Divide voltage by current to calculate resistance. Resistance is measured in ohms. In the example, two-hundred volts divided by four amps equals fifty ohms. 4 To get ohms of resistance, measure the end point. at the endpoint we have 100 volts and 2 amps=50 ohms. therefore we have 100 ohms of resistance
What is voltage of a circuit with 15 amps of current andtoaster with 8ohms of resistance?
V=I*R Where: V is voltage I is the current in ampers R is resistance in ohms. So, if the current is 15 A and the resistance is 5 ohms, then the voltage must be 15 A *5 ohms = 75 V.
What are electrical measurements based on?
voltage (volts) current (amps) resistance (ohms)
What is the voltage if R equals 7 ohms and I equals 2 amps?
14v
What is the voltage drop through a resistor of 6 ohms (2 amps)?
12 volts
