Why the iron box takes more power?
It has low resistance so takes more current.. hence the power
Does heat come from the amps or the volts?
By driving current through a resistance, we create heat. But it takes voltage to drive current through a resistance. In that light, it takes both voltage and current to drive a resistance heater and get it hot. Power (watts) is current (amps) times voltage (volts). But power is also current squared (I2) times resistance (ohms), or I2R. Power is also voltage squared (E2) divided by resistance (ohms) or E2/R. To increase current through a given resistance (like a resistive heating element) you have to increase the voltage. Voltage, current and resistance are "locked" in a fixed arrangement called Ohm's law. It's a relationship that takes this form: E = I x R, or I = E/R, or R = E/I As power is amps times volts (P = I x E), we can answer the question asked here. Question: "Does heat come from the amps or the volts?" Answer: "Yes."
How can the CN Tower be struck by lightning but rarely get damaged?
It has lightning arrestors, which provide a low resistance path to ground (electric current always takes the path of least resistance).
How much is the chance of death due to 0.4Ampere current?
A 0.4 ampere current thru the body can kill, but it normally takes a fairly high voltage to get that current thru the skin, which has high resistance.
What is the resistance of a circuit that takes a current of 0.5A when the voltage to the circuit is 40v?
The formula you are looking for is Ohms = Volts/Amps. R = E/I.
How do you calculate inductive time constant?
The inductive time constant (L/R) is calculated by dividing the inductance of the inductor (L) by the resistance of the circuit (R). It represents the time it takes for the current in the circuit to reach approximately 63.2% of its maximum value during the charging or discharging of the inductor.
What is a connection that allows current to take the path of least resistant?
Current will tend to take the path of least resistance in any case. That's its nature. A short circuit (or "short") is a low resistance current path that current will follow if it appears.
How can one calculate a salary increase based on inflation?
To calculate a salary increase based on inflation, you can use the formula: New Salary Current Salary (Current Salary x Inflation Rate). This formula takes into account the current salary and the rate of inflation to determine the new salary amount.
What determines how severe an electric shock will be?
The severity of an electric shock is determined by the amount of current that passes through the body, the path the current takes, and the duration of the shock. Factors such as voltage, resistance of the body, and individual health can also influence how severe the shock will be.
How can you measure the thickness of cement sheet electricaly?
To measure the thickness of a cement sheet electrically, you can use an ultrasonic thickness gauge. This device emits ultrasonic waves that travel through the material; by measuring the time it takes for the waves to return after reflecting off the back surface, the gauge can calculate the thickness of the cement sheet. Alternatively, electrical resistance measurements can be employed, where a current is passed through the sheet and the resistance is measured; changes in resistance can indicate variations in thickness.
In a circuit where is the voltage drop?
In a circuit, the voltage drop is located wherever there is resistance. Ohm's law: voltage = resistance * current; so without resistance there can be no voltage drop, with resistance there is.
What is the resistance of an electric lamp that takes in a current of 0.40 ampere when 110 volts is applied?
Ohm's Law: Resistance is voltage divided by current 110 volts divided by 0.4 amperes is 275 ohms.
