Electric Potential
What is a ohms?
A motor with an operating resistance of 40 ohms is connected to a voltage source. The current in the circuit is 10 A. This is the voltage of the source.
What is 400 V?
A car battery causes a current of 3.0 A through a lamp and produces 13 V across it. This is the power used by the lamp.
What is 39 W?
This is a device designed to open an overloaded circuit and prevent overheating.
What is a circuit breaker
This is described as a device with specific resistance and is used to control current.
What is a resistor?
This is the flow of charged particles
What is electrical current?
The flow of electric charge or current equal to one coulomb per second is this.
What is an Ampere?
This is the formula for power
What is P=IV?
What is a series circuit?
This is the rate at which an electrical device converts energy from one form to another.
What is electrical power?
If the leaves of an electroscope spread apart, this is what it means
What is the leaves of the electroscope have received a charge?
Electric field lines with positive charges go in this direction and those with negative charges go in this direction.
What is away from and what is towards respectfully?
A lightbulb uses 600 W of power when connected across 15 V. What is the current drawn by the lightbulb?
What is 4 A?
A circuit that has two or more branches for electrons to follow is a
What is a parallel circuit?
This is a large discharge of static electricity.
What is lightning?
This is conservation of charges.
What is the total charge before and after charging remains the same
A lamp draws a current of 4 A when it is connected to a 200 V source. This is the resistance of the lamp
What is 50 Ohms?
What is 50 V?
In this circuit, if a bulb burns out, all of the bulbs burn out.
What is a series circuit?
A material through which electrons do NOT easily flow is this
What is an insulator?
The electric charge that has accumulated on an object is referred to as this.
What is static electricity?
An area with excess electrons has a net this charge; an area with a deficit of electrons has a net this charge.
What is negative and positive respectfully?
This is the energy in Joules if the Power of an engine is 3000 J and it operates for 5 minutes.
What is 900,000 J?
In this circuit, if another bulb is added the current can choose to make it brighter
What is a battery?
