Charge!
This property determines how strongly an object is attracted or repelled by other charged objects.
electric charge
Voltage = Current * Resistance
What is Ohm's Law?
What does a battery symbol look like?
___ -
Describe the characteristics of a series circuit
In a series circuit, components are connected in a single path, and the same current flows through each. Itotal = I1 = I2 = I3
This is the process by which electric charge is transferred in a material through direct contact.
conduction.
If a circuit has a resistance of 5 ohms and a current of 2 amperes, what is the voltage?
V = 10 volts
What does a switch symbol look like?
How does the brightness of bulbs in a parallel circuit compare to bulbs in a series circuit?
Bulbs in a parallel circuit are equally bright, while bulbs in a series circuit share the same brightness.
What are the two types of electric charge?
Positive and negative.
What units are used to measure resistance? (name + symbol)
Ohms (Ω)
Explain how static electricity can build up on a balloon.
Rubbing the balloon transfers electrons from hair to the balloon, creating an imbalance of charge.
What is the purpose of a switch in an electrical circuit?
A switch is used to control the flow of current by opening or closing the circuit.
Explain the concept of grounding in relation to static electricity
Grounding allows excess charge to flow into the Earth, neutralizing an object.
How does increasing resistance in a circuit affect the current?
Increasing resistance decreases the current (I).
Why do certain materials become charged when rubbed together?
The friction between materials causes the transfer of electrons, leading to a buildup of charge.
A parallel circuit consists of a 4-ohm resistor, a 6-ohm resistor, and an 8-ohm resistor. Calculate the current flowing through the circuit when connected to a 20-volt battery.
I = 10.81 A
