Circuit analogies use real life objects and concepts to represent components or processes that function similarly in electric circuits. In a hydraulic circuit, the pump is removed and replaced with a much stronger pump. What would this be analogous to in an electric circuit?

Pressure in a water pump system is analogous to what conceptin an electrical circuit?

A narrow pipe in a water system is analogous to what concept in an electrical circuit?

Copy the electric terms listed below into your notebook. Write the water(hydraulic) related term from the column of terms on the right that besttypifies each electric term next to it. For each pair of terms, describe whyyou think they are similar.(a) load (1) pump(b) switch (2) pressure(c) electric current (3) pipe(d) voltage (4) water wheel(e) battery (5) valve(f) conductor (wire) (6) flow rate2. Draw a circuit diagram using symbols. Include a battery, a switch, a lamp,an ammeter, and conducting wires. Add arrows to show the direction ofthe flow of electrons. Describe the function of each part of the circuit.3. Explain how to connect a voltmeter to a circuit to measure the voltageacross a light bulb. Use a sketch to clarify your explanation.4. Apply Predict which current will be greater, the current passing throughan electric iron or the current passing through an electric razor, when eachis plugged into a 120 V outlet. Explain how you made your prediction.5. Thinking Critically If a circuit contains a 12 V battery, a switch, and alight bulb, what is the voltage across the light bulb?278 MHR • Electrical Principles and TechnologiesAn arrow labelled with thesymbol e is often used toindicate the direction ofelectrical charge move-ment in a circuit.

Circuit analogies use real life objects and concepts to represent components or processes that function similarly in electric circuits. Along a closed loop of road, a camera is installed that records how many cars are moving past it at a given time. In the highway analogy, cars are analogous to charge carriers. What would be the analogous electric circuit component for this camera?

An electric circuit is:carried by protons and electrons and is either positive or negative.1the movement of electrons around a circuit.2a measure of how difficult it is for charges to move.3a closed pathway made from a conducting material.4Flag for laterPrevious7 of 19Next
