a 5-Ω, a 10-Ω, and a 15-Ω resistor are connected in parallel to a power source. if another resistor is added to this circuit in parallel, what happens to the current through the other resistors?
if another resistor is added to this circuit in parallel, the total current through the other resistors increases.
a 5-Ω, a 10-Ω, and a 15-Ω resistor are connected in series to a power source. if another resistor is added to this circuit in series, what happens to the current through the other resistors?
if another resistor is added to this circuit in series, the total current through the other resistors decreases.
a 5-Ω, a 10-Ω, and a 15-Ω resistor are connected in series to a power source. which resistor has the most current passing through it?
no one resistor has more current passing through it than another. since in a series circuit there is one path through the circuit, the current stays the same throughout.
____________ circuits are more suitable for house wiring.
parallel
in a ______________ circuit adding a resistor decreases the total resistance.
parallel
in a ______________ circuit if the current in one resistor goes to zero, the current through all other resistors remains the same.
parallel
in a ______________ circuit the equivalent resistance is equal to the sum of the individual resistances.
parallel
in a ______________ circuit the voltage drop is the same across each resistor.
parallel
in a ______________ circuit adding a resistor increases the total resistance.
series
in a ______________ circuit if the current in one resistor goes to zero, there is no current in the entire circuit.
series
in a ______________ circuit the current is the same throughout.
series
in a ______________ circuit the voltage drop is proportional to the resistance.
series
a 5-Ω, a 10-Ω, and a 15-Ω resistor are connected in series to a power source. which resistor has the largest potential difference across it?
the 15-Ω resistor has the largest potential difference, since V = IR.
a 5-Ω, a 10-Ω, and a 15-Ω resistor are connected in parallel to a power source. which resistor has the most current passing through it?
the 5-Ω resistor has the most current passing through it, since I = V/R.
a 5-Ω, a 10-Ω, and a 15-Ω resistor are connected in parallel to a power source. which resistor has the largest potential difference across it?
no one resistor has a larger potential difference across it, since in parallel there are multiple paths through the circuit, so the voltage drop is the same for each resistor.
two resistors are wired in series. in another circuit, the same two resistors are wired in parallel. in which circuit is the equivalent resistance greater?
the equivalent resistance is greater in a series circuit.
