Current
This is the unit for current
What is Amps (A)?
This is the unit for resistance
What is Ohms?
This is the unit of electrical power
What is Watts (W)?
The number of paths for current in a series circuit
What is one?
The number of paths for current in a parallel circuit
What is more than one?
This is the equation for current
What is I = delta q / delta t
This is the equation for Ohm's Law
What is V = I x R?
This is how the brightness of a light bulb is related to electrical power
What is the greater the electrical power, the brighter the bulb?
This is what happens when one bulb burns out in a series circuit of three bulbs
What is all of the bulbs go out (stop working)?
This is what happens when one bulb burns out in a parallel circuit of three bulbs
What is the other two bulbs keep working?
This type of current is provided by batteries
What is direct current (DC)?
This is the relationship between voltage and current, according to Ohm's Law
What is a direct relationship?
This is the power of a circuit with a voltage of 8 V and a current of 0.45 A.
This what happens to the brightness of bulbs when you connect more of them in series
What is get dimmer (less bright)?
This what happens to the brightness of bulbs when you connect more of them in parallel
What is stay the same brightness?
This type of current is provided by electrical outlets
What is alternating current (AC)?
DAILY DOUBLE!
This is the relationship between resistance and current, according to Ohm's Law
What is an inverse relationship?
What is 1.36 Amps?
This is the equivalent (total) resistance of three resistors in series of 10 Ohms, 15 Ohms, and 18 Ohms
What is 43 Ohms?
This is the equivalent (total) resistance of three resistors in parallel of 12 Ohms, 13 Ohms, and 14 Ohms
What is 4.3 Ohms?
The time it takes for 0.5 C of charge to flow with a current of 0.30 A
A power supply of 24 V supplies 9 A of current to a circuit. This is the resistance of that circuit.
What is 2.67 Ohms?
This is the resistance of a 40 W bulb plugged into a 120 V electrical outlet.
What is 360 (or 400) Ohms.
This is the current in a circuit with a 24 V battery and three resistors in series- 8 Ohms, 12 Ohms, 20 Ohms, and this is a correct diagram of the circuit.
