What is Kirchoff's Voltage Law?

• The total voltage around a closed loop in a circuit is equal to the product of the voltage drops within that loop.
• Kirchoff's Voltage Law states that the voltage across a resistor is directly proportional to the current passing through it.
• Kirchoff's Voltage Law is only applicable to circuits with a single loop.
• The total voltage around a closed loop in a circuit is equal to 0, the sum of the voltage drops within that loop will equal the voltage of the batteries

Answer explanation

What is Kirchoff's current law?

• The current entering a junction is greater than the current leaving the junction
• Total current entering a junction is equal to the total current leaving the junction
• The total current in a loop will be zero, the current of the battery will be positive and resistors will subtract their resistance

• The total current entering a junction is unrelated to the total current leaving the junction

Which statement describes voltage in a series circuit?

• voltage is the same everywhere

• voltage across the resistors are all the same

• resistors contribute positive voltage to a circuit

In a series circuit current

• varies depending on the resistance
• increases with each component
• decreases with each component
• stays the same throughout the loop
