SOLUTIONS
◉ In a series circuit there is ... Flow . Answer: One path for current to
flow
◉ Voltage is equal to ... Answer: Pressure
◉ What is a resistor? Answer: An electrical component that limits
current to a safe value
Drops voltage to a required value
Absorbs and Dissipates Heat
◉ In what circuit does the total current = the sum of the individual
branch currents Answer: Parallel Circuit
◉ True or False: When Voltage goes up, current goes up and vice versa
Answer: True
, ◉ What two variables in Ohm's law are proportional to each other?
Answer: Voltage and Current
(If voltage goes up, current goes up and vice versa)
◉ What two variables in Ohm's law are inversely proportional to each
other? Answer: Resistance and Current
(If resistance goes up, current goes down)
◉ In what circuit is the total resistance always lower than the smallest
branch in the circuit? Answer: Parallel Circuit
◉ What are the rules for a parallel circuit? Answer: Voltage stays the
same
Current adds up for total amount
Resistance Total is always smaller than lowest branch
Power adds up for total
◉ What are the rules for a series circuit? Answer: Voltage adds up for
total
Current stays the same throughout
Resistance adds up for total
Power adds up for total
