Tom notes that the the bulb has an effective resistance of 5.0 Ω, that the voltmeter reads 2.0 V and that the ammeter reads 3.5 A. a) State Kirchoff's First Circuit Law. What implications does it have for the charge entering and leaving a circuit junction? [2] b) State Kirchoff's Second Circuit Law. [1] c) Calculate R1. [1] d) Calculate R2. [3] e) Calculate the power dissipated by the bulb. [1]

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
