WebWith the switch in the circuit of 27.4a closed, there is no current in R2 because the current has an alternate zero-resistance path through the switch. There is current in R1, and this current is measured with the ammeter (a device for measuring current) at the bottom of the circuit. If the switch is opened (27.4b), there is current in R2. WebYou'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: In fig. 4-48, assume that the value of R2 has increased but not open. What happens to. a. The total resistance of R1= b. The series current= c. The Voltage drop across R2= d. The Voltage drop across R1 and R2=. gallery night milwaukee third ward
