Which resistor had the smallest current through it when the v was 12v?
To determine which resistor had the smallest current through it when the voltage (v) was 12V, we can apply Ohm's Law (I = V/R). The resistor with the highest resistance (R) will have the smallest current (I) for a given voltage. Therefore, if you know the values of the resistors in the circuit, the one with the highest resistance will have the smallest current flowing through it when 12V is applied.
What is the current when the voltage is 18 volts and the resistance is 6 ohms?
V=i*r=2*6=12v
When a 3 ohm resistor draws a current of 4 A when hooked up to a battery of unknown voltage what is the battery's voltage and what is the power dissipated by the resistor?
Voltage can be calculated using Ohm's Law:Voltage = Current (A) x Resistance (Ω)Voltage = 4A x 3Ω = 12 VoltsTherefore, the battery is a 12 Volts.The power dissipated is Voltage x CurrentPower = 4A x 12V = 48 Watts

What is the resistance when a bulb has a current of 5 amps and a voltage of 12 volts?
The resistance can be calculated using Ohm's Law, which states that resistance (R) equals voltage (V) divided by current (I). In this case, R = 12V / 5A = 2.4 ohms.
When a 12 V battery is connected across an unknown resister there is a current of 2.5 mA in the circuit find the value of the resistance of the resistor?
Resistance = voltage / current = 12V / 2.5mA = 12V / (2.5 x 10-3 A) = 4.8 x 103 ohm
If the voltage is increased and current remains the same, what happens to the resistance?
According to ohms law (R=V/I) if voltage increases the resistance also increases .For example: If voltage (V) becomes 2 times the resistance (R) also increases becomes 2 times keeping the current (I) same
How do you compute wattage?
Wattage or power rating of a product can be calculated by multiplying voltage rating and current rating. (Power = Voltage x Current). e.g. if device is working at 12V and 2A is the current rating. It is 24Watt. Since Voltage = Current x Resistance , for a resistive load power can also be calculated by Power = Current x Current x Resistance = I^2 x R = I square R
Electromagnet current of o5 a supply is 12v what resistance does the electromagnet have?
Using Ohm's Law (V = I * R), where V is voltage, I is current, and R is resistance, we can rearrange the formula to solve for resistance: R = V / I. In this case, R = 12V / 0.5A = 24 ohms. So the resistance of the electromagnet is 24 ohms.
How do the currents produced by a 1.5v flashlight cell and a 12v car battery compare?
The current produced by a 1.5V flashlight cell would be lower than the current produced by a 12V car battery. This is because current is directly proportional to voltage in a circuit with constant resistance, following Ohm's Law (V = IR). Therefore, the higher voltage of the 12V car battery would result in a higher current compared to the 1.5V flashlight cell.
Determine the power dissipated if the voltage supplied to a circuit is 12V and the current measured is 3A?
The power dissipated by a circuit with a voltage of 12V and a current of 3A is 36W. Watts is Volts times Amps.
What is output voltage of 12v 5watt solar panel?
The output voltage of 12V 5W solar panel is 12V. The current is 0,41667A. These values are normaly calculated with 1000W/m2 of solar radiation.
Can you use output 12v 5A for 12v 3.0A?
Yes, you can use a 12V 5A output for a device that requires 12V 3.0A. The device will only draw the current it needs, so having a higher current rating in the power supply is fine. Just make sure the voltage matches and the polarity is correct.
Why would there be 12v between the negative cable and the post after all fuses are pulled?
Its normal. There's two components to electrical power: voltage and current. A voltage is merely a "potential" to do electrical work. The amount of resistance in a circuit with respect to the amount of potential is what determines how much current flows. Its simple ohms law: Voltage = Current * Resistance, Power = Voltage * Current. Pulling the fuses out of the fuse box leaves an open circuit, which is an infinite amount of resistance. So by pulling your fuses, you prevent current from flowing, but you haven't taken away your battery's potential to do work (its voltage.) The voltage is always there as long as the battery is charged, but no current will flow or power be realized unless you reduce that resistance to something less than infinite by connecting a circuit to it (or in this case, completing the circuit again by replacing the fuses.)
