Studied the powerpoint slide of saftey equipment needed and why we need to wear Personal Protection equiptment such as boots and overalls.
This week in practical sessions I learnt the meanings and how to measure Voltage Drop, the avaliable voltage, Amperage, resistance and Watts.
I learnt how to build an individual circuit which had a : Battery, Fuse, Switch and bulb
Then carried out circuit test.
Test 1: Avaliable voltage
Avaliable voltage is the amount of voltage at the power supply.
13.33V at the power supply, 13.31V after the switch and 0V after the light bulb
Test 2: Voltage drop
Voltage drop is the decrease in voltage along the conductor where voltage is flowing.
0.2v to the switch , 0vinput of switch to output of switch, 0v output of switch to input of bulb, 10.70vinput of bulb to output of the bulb, 0v output of bulb to Neg of power supply
Test 3: Amperage
Amerage is a group of electrons moving along the conductor which gives flow through the circuit.
0.28amps wire before light bulb
Test 4: Resistance.
Resistance is the flow of electrons
Calculating resistance using Ohms Law
V / A x R 10.72 / 0.28 = 38.285
Test 5: watts
Power Law W / V x A
In the last week we have gone over individual circuits , series circuits , parallel circuits. Learning how to calculate using formulars and how to wire the circuits . Also using a multi meter to measure the Ohms and And Amps in the circuit.
