Question: Use Kirchhoff s loop theorem to explain why a 60 W lightbulb
Use Kirchhoff’s loop theorem to explain why a 60-W lightbulb produces more light than one rated at 100 W when they are connected in series to a 120-V source.
Answer to relevant QuestionsUse both of Kirchhoff’s theorems to explain why a 60-W lightbulb produces less light than one rated at 100 W when they are connected in parallel to a 120-V source. If designed properly, a good ammeter should have a very small resistance. Why? Explain clearly, using Kirchhoff’s laws. Three identical resistors are connected to a battery. Two are wired in parallel, and that combination is followed in series by the third resistor. Which resistor has (a) The largest current, (b) The largest voltage, and ...Suppose, in Exercise 14, that another 2.0-Ω resistor is in series with one in the lower branch. (a) Redraw the circuit and predict how the currents in the three different arms will change (increase, decrease, or stay the ...Apply Kirchhoff’s rules to the circuit in Fig. 18.31 to find the current in each resistor.
