How are laws derived from case law?

"Laws" are not derived from "case law" - DECISIONS are derived from case law.


Is electric current a basic quantity or a derived quantity?

Current is a basic quantity, measured in amperes.


The law is derived from three main sources what are they?

Law is derived from Common Law, Statutory Law, and Administrativel Law.


What is the method for calculating amperes and current?

To calculate amperes, you can use Ohm's Law: amperes = voltage ÷ resistance. Current is the flow of electric charge, measured in amperes, that passes through a conductor in a unit of time. You can measure current using an ammeter in a circuit.


How could newton's third law of motion can be derived from second law?

I don't think it can be derived.


What is the current in a copper wire that has a resistance of 3 ohms and is connected to a 9-volt electrical source?

3 amperes. Ohm's law: Voltage is ohms times amperes.


Formula for watts and amps?

power in watts = voltage in volts x current in amps. or power in watts = current in amps x (resistance in ohms) squared i think what you meant was power in watts =(current in amps)squared x resistance in ohms


How do you Calculate the voltage of a battery if the resistance is 20hms and the current is 0.35 amperes?

Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.


What is the equation of resistance?

Ohm's Law: Resistance in ohms is voltage in volts divided by current in amperes.


What the equation of resistance?

Ohm's Law: Resistance in ohms is voltage in volts divided by current in amperes.


What is the generator's voltage if the motor has resistance of 28 ohms and the current is 3.8 amperes?

Ohm's Law: Voltage is resistance time current So, 28 ohms and 3.8 amperes means 106.4 volts.


What does scientific law?

The relationships of the theory from which its derived.
