This ceramic accent coffee mug speaks to anyone who finds humor in equations and comfort in a strong brew. The mug’s playful print — featuring the classic V = IR formula — turns an everyday coffee break into a small, clever moment: a nod to physicists, electricians, and anyone who measures life in volts and amps. Thick-walled ceramic and a glossy color-contrast interior make each sip feel deliberate. It holds a generous pour, keeps colors sharp through washes, and handles microwave reheats without fuss. Set it on your workbench, desk, or kitchen counter and let it start conversations with people who appreciate technical wit and a good cup of coffee.
