When the potential difference across a lamp is 3.3V the current is 0.15 calculate the resistance of the lamp and give the unit
marissa [1.9K]

Answer:

22Ω

Explanation:

Given parameters:

Potential difference  = 3.3V

Current  = 0.15A

Unknown:

Resistance  = ?

Solution:

According to ohm's law, potential difference, current and resistance are related by the expression below;

             V = I R

where V is the voltage

           I is the current

          R is the resistance

          3.3 = 0.15 x R

             R = \frac{3.3}{0.15}   = 22Ω

Which of the following pairs of reactants is not correctly listed with its product solution? A. Strong acid-strong base reactant
gizmo_the_mogwai [7]
<span>It makes no difference which reactant is placed first, a strong acid combined stoichiometrically with a strong base will produce a neutral solution. Due to hydrolysis, a weak acid and strong base produce a basic solution when combined stoichiometrically, and a weak base and strong acid produce an acidic solution when combined stoichiometrically

Mark as brainlist please if correct! BTW have a blessed day!</span>
