Any Material Suitable for carrying electrical current
What is a CONDUCTOR.
This is how many paths current can take in a series circuit.
What is ONE
In a parallel circuit, what happens if one branch is removed or disconnected?
The other branches continue to function normally.
When batteries are connected in series, what happens to the total voltage?
It adds up
When batteries are connected in parallel, what happens to the total voltage?
It stays the same as one battery
The ability or capacity to do work.
What is ENERGY
This is what happens when one resistor in a series circuit burns out.
What is an OPEN.
What happens to total resistance when more resistors are added in parallel?
Total resistance decreases.
Two 6V batteries are connected in series. What is the total voltage?
12V
Two 12V batteries are connected in parallel. What is the total voltage?
12V
The unit of electrical resistance
What is an OHM
Adding the resistors up R1 + R2 + R3....
How is Total Resistance Calculated
A parallel circuit has three resistors: 10Ω, 20Ω, and 30Ω. Which resistor carries the most current?
The 10Ω resistor (lowest resistance, highest current).
If three 9V batteries are connected in series, what is the total voltage?
27V
What is the main advantage of connecting batteries in parallel?
Increased Battery Life (capacity)
Two or more primary or secondary cells connected together electrically.
What is a BATTERY
1.2A of current and a total resistance of 10ohms gives this total voltage source.
What is 12Volts
A parallel circuit has two resistors, 6Ω and 12Ω. What is the total resistance?
4Ω (1/RT = 1/6 + 1/12 → RT = 4Ω)
If four 1.5V batteries are connected in series, but one is installed backward, what is the total voltage?
3V
If three 9V batteries are connected in parallel, what is the total voltage?
9V
A variable Resistor.
What is a RHEOSTAT
A series circuit has 3 resistors, (4ohms, 6 ohms and 10ohms) with a source of 40Volts. This is the total voltage drop across the 6ohm resistor.
What is 12V.
A 24V battery is connected to a parallel circuit with three resistors: 8Ω, 12Ω, and 24Ω. What is the total current drawn from the battery?
6.5A (I1 = 3A, I2 = 2A, I3 = 1.5A, Total I = 3A + 2A + 1.5A = 6.5A)
A series battery pack consists of five 2V cells. If one cell fails and produces no voltage, what is the total voltage?
8V
If two 6V, 10Ah batteries are connected in parallel, what is the total capacity in amp-hours?
20Ah (Capacity adds in parallel: 10Ah + 10Ah = 20Ah)
