1. Consider a square that is composed of four 100 ohm resistors connected together. A fifth 100 ohm resistor is connected across the diagonal of the square. This arrangement is called a bridge circuit. (a) A 10 V battery is connected to the two corners of the square, which are themselves connected to the 100 ohm diagonal resistor. What current flows from this battery

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
