Draw a circuit diagram to represent each description below. ***You may do this on paper & send a picture.

a. An AC power supply connected to a resistor and a light bulb on separate branches of a parallel circuit. Also, this circuit contains a switch that can control each load individually, an ammeter measuring the current flowing through the resistor, and a voltmeter measuring the potential difference across the light bulb. (3 marks)

 

What happens when an ammeter is set up in a parallel connection with the part of the circuit where you want to measure current?

(a) The ammeter gets a correct reading.

(b) The ammeter damages the circuit's voltage source.

(c) The ammeter reverses the current flow through the circuit.

(d) The ammeter creates a short circuit.

How to answer the questions:

Total current in the circuit = 2A

For the circuit above... Find the equivalent resistance, the total voltage and the current and voltage across each resistor.

Dieting is common in our society and everyone wants a piece of the action. So many diets are available to choose from if someone wants to change their health; e.g., lose weight. Often times, diets are promoted with claims of great success.

For the purposes of this assignment, you are to choose a particular diet and analyze it in terms of scientific evidence, or lack thereof. Then, you are to design a controlled experiment to test a hypothesis based on this diet. The experiment must include multiple individuals within a control and experimental group. You must specify how you will measure the outcome of the experiment identifying both the independent and dependent variables. You must describe the potential outcomes of the experiment in terms of supporting the hypothesis.
