Find the currents in the circuit using Kirchhoff’s Laws.

2:34 ull 4G I moodle1.du.edu.om An RTD forms one arm of a Wheatstone bridge as shown in the figure. The RTD is used to measure a temperature with the bridge is operated in a balanced mode. The RTD has a resistance of 252 at a temperature of 0°C and a thermal coefficient of resistance a=0.003925C-1. The value of the variable resistance R, must be set to 41.485 Q to balance the bridge circuit. Determine the temperature measured by the RTD where R2=R3=1002 R2 R3 RTD RRTD E, Select one: O a. 4200

What is resistance? What is a node? What is a closed loop?

The wires here have zero resistance. Thus, for currents that travel along a wire that has no circuitelement, you can safely omit it and simplify the circuit. After, you can use the Kirchhoff's rules.

Two coils are placed close to each other as shown in the figure. The coil on the left is connected to a battery and a switch, and the coil on the right is connected to a resistor.What is the direction of the current in the resistori. an instant after closing the switch?ii. after the switch has been closed for several seconds?iii. an instant after opening the switch?Choose your answers betweento. on the leftb. on the rightc. the current is zero.And clearly explain the reason for your answer.
