A microwave oven uses 1200 W of power The voltage source is 120 V What is the current flowing through the microwave?
10 The typical formula for this is. P = VI. I = P/V = 1200 /120 =10 A Hence, one would think that the answer is 10 A.
However, this formula applies only for DC current. For AC current,
P=VI cos (theta) where theta is the phase difference between V and I. This phase difference is created by the inductances inside the microwave oven. This phase difference is probably mentioned on the specifications of the microwave.
Otherwise another specification maybe mentioned called "MVA". Power (measured in MVA) = V * I Using this , we can directly measure the I.
However, in the absence of either of the two additional information, it is impossible to fully find I.

What is clamping voltage?
The maximum amount of voltage that a surge protector will allow through itself before it will suppress the power surge. When the device reaches its clamping voltage, it blocks any further current from flowing through the device and into a computer system or other electronic device.

Does voltage vs current graph passes through origin?
Yes. While it isn't clear what device you are talking about, and different devices have different characteristic curves (for example, a straight line for a resistor), a voltage is required for a current to flow, so if there is no voltage, there won't be any current, either.
What is the effect on current through a circuit of steady resistance when the voltage is doubled?
The current will increase and will flow more. If voltage increases, current must increase.
One way to make current is to use a what?
You can apply a potential difference across a wire to cause a current to flow through. Ohm's Law allows you to calculate the amount of current based on the voltage supplied and the resistance of the circuit. I = current V = voltage or potential difference R = resistance I = V/R
What is capacitive effect in antenna?
The capacitive effect is an element's opposition to a change in AC voltage. The resistor will develop a positively charged current at it flows through a capacitor. This will prevent a change in the initial voltage.
What microwave oven uses 1200 W of power The voltage source is 120 V What is the current flowing through the microwave?
To find the current flowing through the microwave, you can use the formula: Power (P) = Voltage (V) x Current (I). Given the power is 1200 W and voltage is 120 V, you can rearrange the formula to solve for current: I = P / V. Therefore, I = 1200 W / 120 V = 10 A. The current flowing through the microwave is 10 amps.
A microwave oven uses 1000 W of power The voltage source is 120V What is the current flowing through the microwave?
I = P/V = 1,000/120 = 81/3 Amp.
How can the current through a material be changed?
The current through a material can be changed by varying the voltage applied across the material. By adjusting the voltage, you can increase or decrease the current flowing through the material. Additionally, changing the resistance of the material can also impact the current flowing through it.
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).
what is current controller voltage source?
A voltage source whose voltage varies proportionally to a current flowing through some other path in the circuit.
What force keep current flowing?
Voltage is the pressure that moves the electrons (current) through a circuit.
What kind of relationship can be concluded about the voltage difference across a resistor and the current flowing through it?
POWER=VI. V=voltage I= current
Which is the dangerous current?
You can't really separate them. It's the current flowing through your body that does the damage, but the value of the current depends on the voltage across your body -the higher the voltage, the higher the resulting current.
What is current coil and voltage coil?
Oh, dude, current coils and voltage coils are just like the Beyoncé and Jay-Z of transformers. The current coil measures the current flowing through a circuit, while the voltage coil measures the voltage across a circuit. They're basically the dynamic duo of electrical measurements, keeping things in check and making sure everything runs smoothly.
What is the relationship between current and voltage in an electrical circuit?
The relationship between current and voltage in an electrical circuit is described by Ohm's Law, which states that the current flowing through a circuit is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the circuit. In simpler terms, as the voltage increases, the current flowing through the circuit also increases, assuming the resistance remains constant.
What is the relationship between voltage and current in an electrical circuit?
The relationship between voltage and current in an electrical circuit is described by Ohm's Law, which states that the current flowing through a circuit is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the circuit. This means that as the voltage increases, the current flowing through the circuit also increases, assuming the resistance remains constant.
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
