Why do I have a voltage reading when light switch is off? Just to recap, a “phantom voltage” is where a wire from a switch to a light or outlet runs next to a permanently live wire, when the switch is off, the AC voltage in the other wire can induce a voltage in the […]
Is current density scalar or vector?
Is current density scalar or vector? Despite being the ratio of two scalar quantities, current density is a vector. And the reason is, because it is. Well… actually, it’s because current density is defined as the product of charge density and velocity for any location in space… Is electricity a vector quantity? Vector of scalar? […]
What do scientists disagree about global warming?
What do scientists disagree about global warming? No. By a large majority, climate scientists agree that average global temperature today is warmer than in pre-industrial times and that human activity is the most significant factor. Today, there is no real disagreement among climate experts that humans are the primary cause of recent global warming. What […]

When did Faraday lose memory?
When did Faraday lose memory? AS TIME WORE ON, HE STRUGGLED WITH MEMORY LOSS. At the age of 48, Faraday’s once-sharp memory started faltering. Stricken by an illness that rendered him unable to work for three years, he wrestled with vertigo, unsteadiness, and other symptoms. Did Michael Faraday win a Nobel Prize? Although Michael Faraday […]
How do you calculate standard reduction potential?
How do you calculate standard reduction potential? The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at the cathode. The minus sign is necessary because oxidation is the reverse of reduction. What is the standard […]
