Kirchhoff's law

Current entering and leaving a point in a circuit should be

• equal

• decreasing

• increasing

"The total current in a parallel circuit equals the sum of the individual branch currents."

• Ohm's Law

• Kirchhoff's Voltage Law

• Kirchhoff's Current Law

What is the correct expression for the currents at the following node?

• I₁+I₂=I₃+I₄

• I₁=I₂+I₃-I₄

• I₁+I₃=I₂+I₄

• I₁-I₃=I₂-I₄

Kirchoff's Laws are used to determine:

• Current and Emf

• Current and Electric potential

• Electric potential and Voltage

• Both b &c

For the circuit shown, the resistances are R₁ > R₂ > R_3. What is true about the current through each resistor?

• I₁ = I₂ = I₃

• I₁ > I₂ > I₃

• I₁ > I₃ > I₂

• I₁ < I₃ < I₂

Any closed path in a circuit is called ______________:

• Loop

• Node

• Branch

• Short

____________ __________ is what actually happens. The electrons flow out of the negative side of the battery, through the circuit, and back to the positive side of the battery.

• Conventional Current

• Ohm's Law

• Electron Flow

• Kirchhoff's Current Law

Combined resistance of 5 Ω and 10 Ω are connected in series is equal to
