Series and parallel circuits

What is a series circuit defined as?

One path for current

Describe how current flows in a series circuit.

Single path, same current

Steps for describing current flow in a series circuit:

1⃣ Current enters the circuit from one end

2⃣ It flows through each component in sequence

3⃣ The current leaves the circuit from the other end

What happens to the current as it flows through each component in a series circuit?

It remains the same

Match the resistor with its voltage drop in the example:

R1 ↔ 2V

R2 ↔ 4V

R3 ↔ 6V

What is the formula for the total voltage in a series circuit?

Vtotal​=V1+V1+V2+V2+......

Match the circuit type with its path for current:

Series ↔ Single

Parallel ↔ Multiple

What is a parallel circuit?

Multiple branches for current

What is the formula for calculating the total current in a parallel circuit?

Itotal​=I1+I1​+I2+I2​+I3+I3​+......

How does voltage differ in parallel and series circuits?

Same in parallel, divides in series

How does current differ in parallel and series circuits?

Divides in parallel, same in series

Steps to calculate the total resistance in a parallel circuit

1⃣ Write the formula: 1Rtotal=Rtotal​1​=1R1+R1​1​+1R2+R2​1​+......

2⃣ Substitute the values of the individual resistances

3⃣ Find a common denominator

4⃣ Add the fractions

5⃣ Invert the result to find RtotalRtotal​

Steps to calculate the total resistance in a parallel circuit

1⃣ List the resistance of each resistor

2⃣ Calculate the reciprocal of each resistance

3⃣ Sum the reciprocals

4⃣ Take the reciprocal of the sum
