How do you find the current rating of a zener diode if the power rating is 500mw and a voltage rating of 10v?
A zener diode with a rating of 500 mW will pass 50 mA at 10 V. (Power = voltage times current)Note: The question appears mis stated, in that it states a rating of 500 MW, not 500 mW. To my knowledge, there is no zener with a rating of 500 MW.
How much current flows through a 12 ohm flashlight bulb operating at 3.0 volts?
Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.
What happens to the current in a circuit if a 10 ohm resistor is removed and replaced by a 20 ohm resistor?
Voltage, current, and resistance can be related by this formula. V = iR, where I is the current. Assuming that the voltage stays constant, current will decrease. Hope this helps!
Will the current I1 in a light bulb connected to 300 V be more or less than the current I2 when the same bulb is connected to 110 V?
R = V / I (Ohms Law) A greater voltage results in more current. In the particular case of a light bulb, the resistance will change with current because its temperature changes. We assume here that the bulb is rated to take 200V.
What is the voltage of a circuit in a toaster with 12.0 amps of current and 8.0 ohms of resistance?
The formula you are looking for is Ohm's Law. Voltage = Current x Resistance (v = I x R). To solve for Current the formula is I = V/R.

What is the power rating of 500 amperes welding machine?
Welding is done with a high current and low voltage. The voltage of a 500 amp welder might be 10 v so the power rating in that case would be 5000 watts.
How much current flows in a 12-watt radio connected to a 120-volt circuit?
Since power = current x voltage, you would divide the power (watts) by the voltage. The answer would be 1/10 amps or .10 amps.
What will be input and output current of 10 KVA 3 phase UPS?
It will depend on input & output voltage, if voltage is same current will remain same
A 10 ohms resistor is connected aross a 12 volt battery How much current is there through the resistor?
Voltage = Current * ResistanceVoltage = 12VResistance = 10 ohmsCurrent = Voltage/ResistanceCurrent = 12V/10 ohmsCurrent = 1.2 Amps
How much current would an applied voltage of 10 volts cause through a resistance of 5 ohms?
10 volts applied to 5 ohms would cause a current flow of 2 amperes. Current = voltage divided by resistance.

What is the voltage if R 5 ohms and you 2 A?
voltage = resistance x current = 5 x 2 = 10 volts
What change occurs on current when voltage is in a circuit is constant and resistance gets double?
Ohms Law: V = IR (or equivalently, I = V/R) if voltage is held constant, then when resistance goes up, current goes down, and vice-versa. Say for instance, the voltage is 10 Volts, and resistance is 5 Ohms. That means the current is 2 Amps. (2 = 10/5) If the resistance is raised to 10 Ohms, then the current drops to 1 Amp. (10 = 10/1)
What is the current 1 if the voltage is 100volts and the resistor is 10ohms?
Ohm's Law: Current is voltage divided by resistance.100 volts divided by 10 ohms is 10 amperes.This is also 1000 watts (power is voltage times current), so do not try it unless you have a resistor, a power supply, and a setup that can handle the power load!
Can you plug a 125-250 appliance into a 120-240 circuit?
all voltage is plus or minus 10% of rating
What is the voltage of microwave with a resistance of 5 ohms and current flowing of 10 amperes?
It looks as if you can use Ohm's Law to calculate this: V=IR (voltage = current x resistance).
