For the circuit on the right, indicate whether the statementsbelow are TRUE or FALSE. If the statement is true, brieflydescribe the evidence from this lab which supports thisstatement. If a statement is false, give a correct statement, and briefly describe the evidence from this lab which supports thisnew statement. (The drawing is a battery with a bulb, line Ais attached to the positive end of the battery and the metal shaftnear the bottom of the glass on the bulb, and line B is attached tothe negative end of the battery and the small knob on the veryend of the bulb.)
a) The current is from the battery, through wire A, through the bulb, and then back to the battery through wireB.
b) Since current is used up by the bulb, the current inwire B is smaller than the current in wire A.
c) The current is toward the bulb in both wires A andB.
d) If wire B is disconnected, but wire A is leftconnected, the bulb will still light, but if wire A is disconnectedand wire B is left connected, the bulb will not light.
e) A current probe will read the same magnitude ifconnected to measure the current in wire A or wire B.
