Question 1

What is the effect of adding resistors in series

Answer 1

• Resistance is increased

* Increases the length of the path taken by the charge carriers

Question 2

What is the relationship of the total resistance with the individual resistances in components in series

Answer 2

• Kirchoff’s second law is V = V1 + V2 + …
• V = IR
• Kirchoff’s first law is I is a constant
• IR = IR1 + IR2 + …
• R = R1 + R2 + …

Question 3

What is the effect of adding resistors in parallel

Answer 3

• Resistance is decreased
• Additional resistor adds another path for the current
• effectively increasing the cross-sectional area
• lowers resistance

Question 4

What is the relationship of the total resistance with the individual resistances in components in parallel

Answer 4

• Kirchhoff’s first law states I = I1 + I2 + …
• Kirchoff’s second law states pd is constant across each resistor and equal to V
• I/V = I/V1 + I/V2 + …
• V = IR
• I/V = 1/R
• 1/R = 1/R1 + 1/R2 + …

Question 5

What is a resistor circuit

Answer 5

Two or more resistors arranged in a way to provide a specific resistance
