Using the Electrical Power Law, which is:
The current (measured in amps) equals the power (measured in watts) divided by the potential difference (measured in volts)
So a light bulb designed to use 60 watts of power when supplied with 120 volts must draw 60 watts divided by 120 volts, which is a current of 0.5 amps.
The same answer could be expressed in a few different ways:
- 500 milliwatts
- 500 mW
- "1/2 an amp" !
What else can I help you with?
What is a resistance of the appliance If 24 amps of current flows through an appliance connected to a 120 v circuit.?
Let R be the resistance, V the voltage, and I the current R = V / I R = 120 / 24 R = 5 ohm
A meter should indicate how many volts when connected to a 100 ohm resistor that has 6 amps of current passing through it?
600 VDC.
How much current flows through a resistor of 285 ohms if the potential difference across the resistor is 122 volts?
Use Ohm's Law, i.e., V=IR here, V=voltage I=current R=resistance
How do you work out amps of current from 230V connected to 534 ohm resister?
you divide the volts by the ohms
A 100-w light bulb is turned on it has an operating voltage of 120 V how much current flows through the bulb?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
How much current flows through a toaster with a resistance of 20 ohms when it is connected to a 110 volt outlet?
Ohm's Law Volts = Current x Resistance Amps = V / R 110 / 20 = 5.5 Amps
What current flows through a 920 watt hairdryer if the voltage is 230 volts?
4 amps
How much current flows through a resistance of 300 ohms if the power source is 15 volts?
Ohm's Law Voltage = Current x Resistance Answer is 15/300
How much current flows in a 12 watt radio connected to a 120 volt supply?
Assuming that you mean connected to 120 Volts (V) supply, start with Power(P)=Current(I) x Voltage(V), and if P=V*I, then I=P/V. I=12W/120V=0.1A or 100mA and that is your current.
How much power flows through a circuit with 1 amp and 120 volts?
The power flowing through the circuit can be calculated using the formula P = I * V, where P is power, I is current, and V is voltage. In this case, P = 1 amp * 120 volts = 120 watts. Therefore, 120 watts of power flows through the circuit.
How much current flows in 10 ohms when connected to 12 volts?
Ohms are the unit of resistance you find in Ohms LAw which says Volts = Amps x Ohms. You can get a voltage drop across a resistance, but would have to know what current is being used and you would have a potentiometer in effect. You are not "converting 12V" to 10V, your are essentially loosing two volts through a resistor.
How many amperes 1.5kw are?
That depends on the voltage which the current flows through. I = P / U I = 1500 / U Where I is the current in Amperes and U is the effective voltage in Volts. (P is the power)
What is a resistance of the appliance If 24 amps of current flows through an appliance connected to a 120 v circuit.?
Let R be the resistance, V the voltage, and I the current R = V / I R = 120 / 24 R = 5 ohm
A meter should indicate how many volts when connected to a 100 ohm resistor that has 6 amps of current passing through it?
600 VDC.
What are the three electrical guantities?
The three electrical quantities are current voltage and resistance. Current is measured in amperes (A) and is the rate at which electricity flows through a conductor. Voltage is measured in volts (V) and is the electrical force pushing the current through the conductor. Resistance is measured in ohms () and is the opposition to the flow of current. Current - measured in amperes (A) Voltage - measured in volts (V) Resistance - measured in ohms ()
What is the current that flows through a 100-w lightbulb if it is connected to a 110-v source?
-10
How many amps in 11.000 volts?
The voltage tells you nothing about the current flow in amps, it's only the pressure sending current through a circuit. If a 11,000 volt supply is not connected to anything, the current is zero.
