Legislation/Induction

Ohm's law describes the mathematical relationship between

• Resistance, current and power

• Power, current and resistance

• Current, voltage and power

• Resistance, current and voltage

When the length and cross sectional area of the conductor is halved then the resistance..........

• will become half

• will be doubled

• remains the same

• will increase by four times

Ohms law states

• VI² = R

• V/I = R²

• R = I/V

• V = IR

According to Ohms Law

• "I" is directly proportional to "V"

• "I" is inversely proportional to "V"

Approximately how many amps of current will flow through a circuit with a 36 V source and 6.8k of resistance?

• 0.00529mA

• 529mA

• 5.29mA

• 52.9mA

P= 3.4kw, I = 20 amps, v = ?

• 170

• 230

• 17

• 1700

The current version of the Electricity Act is dated what year?

• 2018

• 2010

• 2007

• 1992

The current cited standard for Electrical Installations is what?

• AS/NZS 2000:2007

• AS/NZS 3000:2018

• AS/NZS 2000:2018

• AS?NZS 3000:2007
