In a series circuit the total current is the same throughout resistors and so:
The voltage is distributed throughout the resistors and so:
and the total resistance can be calculated by adding up the resistors resistance:
First thing is to calculate the total resistance and so:
And by Omh's law V=IR we have:
And so the total current of the circuit is 1.2 amps i.e. 1.2 A.
I believe it was the Greek on astronomy or something close to that that discovered that the world was round.
Work = Force x displacement
W= 250 x 15
W= 3750 Nm
A. NaCl (salt) because it is an ionic compound which will dissociate in water and make the water conduct electricity
Explanation:
Sodium chloride (NaCl) is an ionic compound and when is dissolved in water sodium (Na⁺) and chlorine (Cl⁻) ions are formed. The ions in water will promote the movement of electrical charges so the solution will conduct electricity.
Sugar (C₆H₁₂O₆) is a covalent compound and will not form ions when is dissolved in water. The sugar solution will not conduct electricity.
